12bolts stopped being put in trucks in 1981. If you want one get one out of a pre-81 truck. I don't think I would worry about it too much unless you are planting slicks on the track. We ran a 82 truck with a 454 putting out about 450hp and sprayed 250 shot of NO2 to it and the tranny went south first. The truck wouldn't/couldn't hook the tires up. What are you doing for traction to hook all of this up?

I have one in a 90 Suburban 5-lug. Will check on gears, but I think it is 3:42s. Louisville,Ky

If you could find out what those gears are and possibly send me some pictures of the whole rear end that would be greatly appreciated
